Saving Data for for loop into a vector

I have a vector of 1801 THRUST data points. I am determining when the THRUST data is less than 0.43 and trying to index at what points this is the case. I am then trying to find the corresponding times. I have another vector, TIME, of the same length. Below is my code, but I cannot get it to print out the indexed times as a vector. Any help is appreciated
for i = 1:1801
if find(THRUST > 0.43)
Y(x) = TIME(i)
end
else Y = NaN
end
end

The loop is likely not necessary.
Try this:
idx = find(THRUST>=0.43, 1, 'first');
Time = TIME(idx);
to get the closest index, or:
idx = find(THRUST>=0.43, 1, 'first');
Time = interp1(THRUST(idx-2:idx), TIME(idx-2:idx), 0.43);
to interpolate to a more precise value, if ‘THRUST’ is never exactly 0.43.
